Hexythiazox; Pesticide Tolerances
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This regulation establishes tolerances for residues of the ovicide/miticide hexythiazox in or on beet, sugar, root, and beet, sugar, dried pulp and establishes tolerances associated with regional registrations for residues on Bermuda grass, forage and Bermuda grass, hay. This regulation also modifies the existing tolerances associated with regional registrations in or on alfalfa, forage; and alfalfa, hay. Gowan Company requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA). The regulation also removes the existing time-limited tolerance for residues on beet, sugar, root because it is superseded by the new beet, sugar, root tolerance and removes the tolerance for residues ``Fruit, citrus group 10'' of 0.35 ppm because it is superseded by the existing tolerance for ``Fruit, citrus group 10-10'' of 0.6 ppm.
DATES: This regulation is effective February 14, 2017. Objections and requests for hearings must be received on or before April 17, 2017, and must be filed in accordance with the instructions provided in 40 CFR part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

Summary of Petitioned-For Tolerance
In the Federal Register of March 16, 2016 (81 FR 14030) (FRL-9942-
86), EPA issued a document pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of three (3) pesticide petitions (PP 5F8396, 5F8412 & 5F8413) by Gowan Company, P.O. Box 5569, Yuma, AZ 85366-5569. These petitions requested that 40 CFR 180.448 be amended by (1) establishing tolerances for residues of the hexythiazox in or on Bermuda grass, forage at 40 parts per million (ppm) (PP 5F8412); Bermuda grass, hay at 70 ppm (PP 5F8412); beet, sugar, dried pulp at 0.60 ppm (PP 5F8413); beet, sugar, molasses at 0.21 ppm (PP 5F8413); beet, sugar, roots at 0.15 ppm (PP 5F8413); and beet, sugar, tops at 1.5 ppm (PP5F8413); and (2) modifying the existing tolerances for residues in or on alfalfa, forage from 15 ppm to 20 ppm (PP 5F8396) and alfalfa, hay from 30 ppm to 60 ppm (PP 5F8396). These documents referenced a summary of the petitions prepared by Gowan Company, the registrant, which are available in the docket, http://www.regulations.gov. Several comments were received in response to the notice of filing, objecting generally to the presence of pesticide residues in food. Because none of the comments provided any information for the Agency to consider in its review of the requested hexythiazox tolerances and because the Agency has concluded based on available data that the tolerances requested meet the FFDCA safety standard, EPA is not granting the commenters' requests to deny the petition.

Aggregate Risk Assessment and Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a tolerance (the legal limit for a pesticide chemical residue in or on a food) only if EPA determines that the tolerance is ``safe.'' Section 408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is reliable information.'' This includes exposure through drinking water and in residential settings, but does not include occupational exposure. Section 408(b)(2)(C) of FFDCA requires EPA to give special consideration to exposure of infants and children to the pesticide chemical residue in establishing a tolerance and to ``ensure that there is a reasonable certainty that no harm will result to infants and children from aggregate exposure to the pesticide chemical residue. . . .''
Consistent with FFDCA section 408(b)(2)(D), and the factors specified in FFDCA section 408(b)(2)(D), EPA has reviewed the available scientific data and other relevant information in support of this action. EPA has sufficient data to assess the hazards of and to make a determination on aggregate exposure for hexythiazox including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with hexythiazox follows.
-
Toxicological Profile
EPA has evaluated the available toxicity data and considered its validity,
Page 10549
completeness, and reliability as well as the relationship of the results of the studies to human risk. EPA has also considered available information concerning the variability of the sensitivities of major identifiable subgroups of consumers, including infants and children.
Hexythiazox has low acute toxicity by the oral, dermal, and inhalation routes of exposure. It produces mild eye irritation and is not a skin irritant or skin sensitizer. Hexythiazox is associated with toxicity of the liver and adrenals following subchronic and chronic exposure to dogs, rats, and mice, with the dog being the most sensitive species. The prenatal developmental studies in rabbits and rats and the 2-generation reproduction study in rats showed no indication of increased susceptibility to in utero or postnatal exposure to hexythiazox. Reproductive toxicity was not observed. There is no concern for immunotoxicity or neurotoxicity following exposure to hexythiazox. The toxicology database for hexythiazox does not show any evidence of treatment-related effects on the immune system.
Hexythiazox is classified as ``Likely to be Carcinogenic to Humans'' based on a treatment-related increase in benign and malignant liver tumors in female mice and the presence of mammary gland tumors (fibroadenomas) in male rats; however, the evidence as a whole was not strong enough to warrant the use of a linear low dose extrapolation model applied to the animal data (Q1*) for a quantitative estimation of human risk because the common liver tumors (benign and malignant) were only observed in high-dose female mice, and benign mammary gland tumors were only observed in high-dose male rats. Since the effects seen in the study that serves as the basis for the chronic reference dose (cRfD) occurred at doses substantially below the lowest dose that induced tumors (and there is no mutagenic concern for hexythiazox), the cRfD is considered protective of all chronic effects, including potential carcinogenicity.
Specific information on the studies received and the nature of the adverse effects caused by hexythiazox as well as the no-observed-
adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-
level (LOAEL) from the toxicity studies can be found at http://www.regulations.gov within the document entitled ``Hexythiazox. Human Health Risk Assessment for Section 3 Registration on Bermuda Grass and Amended Registrations for Use on Beet, sugars, Alfalfa, and Potatoes,'' which can be found in docket ID numbers EPA-HQ-OPP-2015-0795, EPA-HQ-
OPP-2015-0796 and EPA-HQ-OPP-2015-0797.

Toxicological Points of Departure/Levels of Concern
Once a pesticide's toxicological profile is determined, EPA identifies toxicological points of departure (POD) and levels of concern to use in evaluating the risk posed by human exposure to the pesticide. For hazards that have a threshold below which there is no appreciable risk, the toxicological POD is used as the basis for derivation of reference values for risk assessment. PODs are developed based on a careful analysis of the doses in each toxicological study to determine the dose at which no adverse effects are observed (the NOAEL) and the lowest dose at which adverse effects of concern are identified (the LOAEL). Uncertainty/safety factors are used in conjunction with the POD to calculate a safe exposure level--generally referred to as a population-adjusted dose (PAD) or a reference dose (RfD)--and a safe margin of exposure (MOE). For non-threshold risks, the Agency assumes that any amount of exposure will lead to some degree of risk. Thus, the Agency estimates risk in terms of the probability of an occurrence of the adverse effect expected in a lifetime. For more information on the general principles EPA uses in risk characterization and a complete description of the risk assessment process, see http://www.epa.gov/pesticides/factsheets/riskassess.htm. A summary of the toxicological endpoints for hexythiazox used for human risk assessment is shown in Table 1 of this unit.

Exposure Assessment
-
Dietary exposure from food and feed uses. In evaluating dietary exposure to hexythiazox, EPA considered exposure under the petitioned-
for tolerances as well as all existing hexythiazox tolerances in 40 CFR 180.448. EPA assessed dietary exposures from hexythiazox in food as follows:
i. Acute exposure. Quantitative acute dietary exposure and risk assessments are performed for a food-use pesticide, if a toxicological study has indicated the possibility of an effect of concern occurring as a result of a 1-day or single exposure. No such effects were identified in the toxicological studies for hexythiazox; therefore, a quantitative acute dietary exposure assessment is unnecessary.
ii. Chronic exposure. In conducting the chronic dietary (food and drinking water) exposure assessment, EPA used the Dietary Exposure Evaluation Model (DEEM-FCID), Version 3.16, which uses food consumption data from the U.S. Department of Agriculture's National Health and Nutrition Examination Survey, What We Eat in America (NHANES/WWEIA) from 2003-2008. As to residue levels in food, EPA used tolerance-level residues, assumed 100 percent crop treated (PCT), and incorporated DEEM 7.81 default processing factors when processing data were not available.
iii. Cancer. Based on the data summarized in Unit III.A., EPA has concluded that a nonlinear RfD approach is appropriate for assessing cancer risk to hexythiazox. Cancer risk was assessed using the same exposure estimates as discussed in Unit III.C.1.ii., Chronic exposure.
iv. Anticipated residue and percent crop treated (PCT) information. EPA did not use anticipated residue and/or PCT information in the dietary assessment for hexythiazox. Tolerance-level residues and/or 100 PCT were assumed for all food commodities.
-
Dietary exposure from drinking water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for hexythiazox in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of hexythiazox. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at http://www.epa.gov/oppefed1/models/water/index.htm.
Because surface water and groundwater estimated drinking water concentrations (EDWCs) from the proposed new uses on Bermuda grass and sugar beets (ranging from 1.29 to 2.78 mug/L) do not produce EDWCs greater than those produced from a recent drinking water assessment (D429192, 9/21/2015) (ranging from 3.5 to 7.3 mug/L) using the Mississippi soybeans scenario, the Agency is relying on the EDWCs from that previous drinking water assessment. Based on that assessment, the EDWCs of hexythiazox for chronic exposures are estimated to be 4.3 ppb for surface water and 2.4 ppb for ground water. The higher of these numbers was directly entered into the dietary exposure model for the chronic dietary risk assessment.
-
From non-dietary exposure. The term ``residential exposure'' is used in this document to refer to non-occupational, non-dietary exposure (e.g., for lawn and garden pest control, indoor pest control, termiticides, and flea and tick control on pets). Hexythiazox is currently registered for the following residential uses, including ornamental landscape plantings, turf, and fruit and nut trees in residential sites.
EPA assessed residential exposure using the following assumptions: Residential handler exposures are expected to be short-term (1 to 30 days) via either the dermal or inhalation routes of exposures. Since a quantitative dermal risk assessment is not needed for hexythiazox, handler MOEs were calculated for the inhalation route of exposure only. Both adults and children may be exposed to hexythiazox residues from contact with treated lawns or treated residential plants. Post application exposures are expected to be short-term (1 to 30 days) and intermediate-term (1 to 6 months) in duration. Adult post-application exposures were not assessed since no quantitative dermal risk assessment is needed for hexythiazox and inhalation exposures are typically negligible in outdoor settings. The exposure assessment for children included incidental oral exposure resulting from transfer of residues from the hands or objects to the mouth, and from incidental ingestion of soil.
Further information regarding EPA standard assumptions and generic inputs for residential exposures may be found at http://www.epa.gov/pesticides/science/residential-exposure-sop.html.
-
Cumulative effects from substances with a common mechanism of toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when considering whether to establish, modify, or revoke a tolerance, the Agency consider ``available information'' concerning the cumulative effects of a particular
Page 10551
pesticide's residues and ``other substances that have a common mechanism of toxicity.''
EPA has not found hexythiazox to share a common mechanism of toxicity with any other substances, and hexythiazox does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action; therefore, EPA has assumed that hexythiazox does not have a common mechanism of toxicity with other substances. For information regarding EPA's efforts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see EPA's Web site at http://www.epa.gov/pesticides/cumulative.
-
-
Safety Factor for Infants and Children
-
In general. Section 408(b)(2)(C) of FFDCA provides that EPA shall apply an additional tenfold (10X) margin of safety for infants and children in the case of threshold effects to account for prenatal and postnatal toxicity and the completeness of the database on toxicity and exposure unless EPA determines based on reliable data that a different margin of safety will be safe for infants and children. This additional margin of safety is commonly referred to as the FQPA Safety Factor (SF). In applying this provision, EPA either retains the default value of 10X, or uses a different additional safety factor when reliable data available to EPA support the choice of a different factor.
-
Prenatal and postnatal sensitivity. The prenatal and postnatal toxicology data base indicates no increased susceptibility of rats or rabbits to in utero and/or postnatal exposure to hexythiazox.
-
Conclusion. EPA has determined that reliable data show the safety of infants and children would be adequately protected if the FQPA SF were reduced to 1X. That decision is based on the following findings:
i. The toxicity database for hexythiazox is complete.
ii. There is no indication that hexythiazox is a neurotoxic chemical and there is no need for a developmental neurotoxicity study or additional UFs to account for neurotoxicity.
iii. There is no evidence that hexythiazox results in increased susceptibility in in utero rats or rabbits in the prenatal developmental studies or in young rats in the 2-generation reproduction study.
iv. There are no residual uncertainties identified in the exposure databases. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to hexythiazox in drinking water. EPA used similarly conservative assumptions to assess post-application exposure of children as well as incidental oral exposure of toddlers. These assessments will not underestimate the exposure and risks posed by hexythiazox.
-
-
Aggregate Risks and Determination of Safety
EPA determines whether acute and chronic dietary pesticide exposures are safe by comparing aggregate exposure estimates to the acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA calculates the lifetime probability of acquiring cancer given the estimated aggregate exposure. Short-, intermediate-, and chronic-term risks are evaluated by comparing the estimated aggregate food, water, and residential exposure to the appropriate PODs to ensure that an adequate MOE exists.
-
Acute risk. An acute aggregate risk assessment takes into account acute exposure estimates from dietary consumption of food and drinking water. No adverse effect resulting from a single oral exposure was identified and no acute dietary endpoint was selected; therefore, hexythiazox is not expected to pose an acute risk.
-
Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic exposure to hexythiazox from food and water will utilize 93% of the cPAD for children 1 to 2 years of age, the population group receiving the greatest exposure. Based on the explanation in Unit III.C.3., regarding residential use patterns, chronic residential exposure to residues of hexythiazox is not expected.
-
Short-term risk. Short-term aggregate exposure takes into account short-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level).
Hexythiazox is currently registered for uses that could result in short-term residential exposure, and the Agency has determined that it is appropriate to aggregate chronic exposure through food and water with short-term residential exposures to hexythiazox. Using the exposure assumptions described in this unit for short-term exposures, EPA has concluded the combined short-term food, drinking water, and residential inhalation exposures result in an aggregate MOE for adults (7,700) that greatly exceeds the LOC of 100, and is not of concern.
-
Intermediate-term risk. Intermediate-term aggregate exposure takes into account intermediate-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level).
Hexythiazox is currently registered for uses that could result in intermediate-term residential exposure, and the Agency has determined that it is appropriate to aggregate chronic exposure through food and water with intermediate-term residential exposures to hexythiazox. Using the exposure assumptions described in this unit for intermediate-
term exposures, EPA has concluded the combined intermediate-term food, drinking water, and residential oral exposures result in an aggregate MOE for children (1,150) that greatly exceeds the LOC of 100, and is not of concern.
-
Aggregate cancer risk for U.S. population. As discussed in Unit III. C.1.iii., EPA concluded that regulation based on the cRfD will be protective for both chronic and carcinogenic risks. As noted in this unit, there are no chronic risks of concern.
-
Determination of safety. Based on these risk assessments, EPA concludes that there is a reasonable certainty that no harm will result to the U.S. general population, or to infants and children from aggregate exposure to hexythiazox residues.
-
-
-
Other Considerations
-
Analytical Enforcement Methodology
An adequate analytical enforcement methodology, high performance liquid chromatography method with UV detection (HPLC/UV), is available to enforce the tolerance expression for hexythiazox and its metabolites containing the PT-1-3 moiety in crop and livestock commodities. This method is listed in the U.S. EPA Index of Residue Analytical Methods under hexythiazox as method AMR-985-87.
-
International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S. tolerances with international standards whenever possible, consistent with U.S. food safety standards and agricultural practices. EPA considers the international maximum residue limits (MRLs) established by the Codex Alimentarius Commission (Codex), as required by FFDCA section 408(b)(4). The Codex Alimentarius is a joint United Nations Food and Agriculture Organization/World Health Organization food standards program, and it is recognized as an international food safety standards-setting
Page 10552
organization in trade agreements to which the United States is a party. EPA may establish a tolerance that is different from a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain the reasons for departing from the Codex level.
The Codex has not established a MRL for hexythiazox for alfalfa, forage and hay; and beet, sugar roots and top.
-
Revisions to Petitioned-For Tolerances
The petitioner requested tolerances for beet, sugar, molasses and beet, sugar, dried pulp based on the raw agricultural commodity (RAC) tolerance level instead of the HAFT (Highest Average Field Trial). Using the HAFT to determine the tolerance for these processed commodities, EPA determined that residues in the molasses would be covered by the tolerance on the beet, sugar, root; therefore, a separate molasses tolerance is not required. Using the HAFT for beet, sugar, dried pulp, EPA determined that the tolerance should be reduced to 0.30 ppm. Beet, sugar, tops are no longer considered a major livestock food commodity for regulatory purposes; therefore, a tolerance is not required for beet, sugar, tops.
-
-
Conclusion
Therefore, tolerances are established for residues of the ovicide/
miticide hexythiazox and its metabolites containing the (4-
chlorophenyl)-4-methyl-2-oxo-3-thiazolidine moiety in or on beet, sugar, root at 0.15 ppm and beet, sugar, dried pulp at 0.30 ppm. Tolerances associated with regional registrations are established for Bermuda grass, forage (EPA Regions 9-10 only) at 40 parts per million (ppm) and Bermuda grass, hay (EPA Regions 9-10 only) at 70 ppm. Also, existing tolerances are modified for residues in or on Alfalfa, forage (EPA Regions 7-11 only) at 20 ppm and Alfalfa, hay (EPA Regions 7-11 only) at 60 ppm.
Because the new tolerance for beet, sugar, root (in 40 CFR 180.448(a)) supersedes the existing time-limited tolerance for beet, sugar, root (in 40 CFR 180.448(b)), the Agency is removing the time-
limited tolerance.
In addition, in the previous rulemaking establishing hexythiazox tolerances, EPA instructed the Federal Register staff to revise the existing entry in the table in paragraph (c) for ``Fruit, citrus group 10 (CA, AZ, TX only)'' at 0.35 ppm to ``Fruit, citrus group 10-10 (CA, AZ, TX only)'' at 0.6 ppm. (April 6, 2016, 81 FR 19891). Instead of revising the existing entry, a separate entry was created for ``Fruit, citrus group 10-10 (CA, AZ, TX only).'' The result is that the table in paragraph (c) now contains two overlapping entries: ``Fruit, citrus group 10 (CA, AZ, TX only)'' of 0.35 ppm and an entry for ``Fruit, citrus group 10-10 (CA, AZ, TX only)'' of 0.6 ppm. Because ``Fruit, citrus group 10 (CA, AZ, TX only)'' is superseded by ``Fruit, citrus group 10-10 (CA, AZ, TX only),'' EPA is removing ``Fruit, citrus group 10 (CA, AZ, TX only)'' as a housekeeping measure.

Statutory and Executive Order Reviews
This action establishes tolerances under FFDCA section 408(d) in response to a petition submitted to the Agency. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled ``Regulatory Planning and Review'' (58 FR 51735, October 4, 1993). Because this action has been exempted from review under Executive Order 12866, this action is not subject to Executive Order 13211, entitled ``Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled ``Protection of Children from Environmental Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997). This action does not contain any information collections subject to OMB approval under the Paperwork Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any special considerations under Executive Order 12898, entitled ``Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations'' (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis of a petition under FFDCA section 408(d), such as the tolerance in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), do not apply.
This action directly regulates growers, food processors, food handlers, and food retailers, not States or tribes, nor does this action alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of FFDCA section 408(n)(4). As such, the Agency has determined that this action will not have a substantial direct effect on States or tribal governments, on the relationship between the national government and the States or tribal governments, or on the distribution of power and responsibilities among the various levels of government or between the Federal Government and Indian tribes. Thus, the Agency has determined that Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 10, 1999) and Executive Order 13175, entitled ``Consultation and Coordination with Indian Tribal Governments'' (65 FR 67249, November 9, 2000) do not apply to this action. In addition, this action does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act (UMRA) (2 U.S.C. 1501 et seq.).
This action does not involve any technical standards that would require Agency consideration of voluntary consensus standards pursuant to section 12(d) of the National Technology Transfer and Advancement Act (NTTAA) (15 U.S.C. 272 note).

This action is not a ``major rule'' as defined by 5 U.S.C. 804(2).
